Born in Nevada in 1901, Milton Erickson grew up on a farm in Wisconsin. As a pioneer in the use of hypnosis, he established hypnosis as a valid and effective therapeutic technique. His books on hypnotherapy, although geared toward health professionals in medicine, dentistry, and psychotherapy, are written in an original and personal style. Both a psychiatrist and a psychologist, Erickson was a member of many national and international professional organizations. At the time of his death in 1980, he was the world's leading practitioner of medical and therapeutic hypnosis.
